[目的]构建一个界面友好、操作方便、通用性强的热带花卉种质资源图文数据库系统,为实现热带花卉种质资源的数字化管理提供技术支撑.[方法]采用C/S架构,以SQL Server 2005为后台数据库,在集成QT的Visual C++可视化开发平台上设计并实现热带花卉种质资源图文数据库系统.[结果]构建了热带花卉种质资源图文数据库系统,实现了热带花卉种质资源数据管理、数据查询、元数据配置、用户管理及数据库维护等功能.[结论]该系统具有兼容性强、可扩展性好、智能化、安全系数高、界面友好、操作方便等优点,为热带花卉数据建立了统一的服务平台,并为规范花卉信息提供了强有力的技术支撑.%[Objective]The present study aimed to construct a datahase system for germplasm resources of tropical flowers in order to provide technical support for digital management of germplasm resources of tropical flowers. The database system was characterized by user-friendly interface, simple operation and versatility. [Method]The database system chose client/server structure as its frame and Microsoft SQL Server 2005 as database and was designed and developed in visual C++ platform integrated with QT. [Result]The database system for germplasm resources of tropical flowers have heen constructed. It has achieved the following functions: data management, data querying, metadata configuration, user management and database maintenance. [Conclusion]The database system for germplasm resources of tropical flowers has advantages of high compatibility, expansibility, high safety coefficient, use-friendly interface and simple operation. The study has established a uniform service platform for germplasm resources of tropical flowers and provides technical support for standardization of information of tropical flowers.
